Valley Water is proposing a supplementary geotechnical exploration at Calero Reservoir to support design of CDSRP. Phase I of the geotechnical investigation was completed in November 2024, and collected information on subsurface conditions near the main dam, spillway, and borrow area. Phase II of the geotechnical investigation would involve drilling of five in-water vertical boreholes to characterize subsurface conditions at a future intake structure and outlet tunnel. |
